I must apologize if your comments do not appear immediately, but I've been forced to start reviewing them again to weed out those that are are platitudes with links to commercial sites - they now outnumber legitimate comments.
About this time every year I have an identity crisis over whether I should continue the blog and/or develop a next lecture/essay topic, and/or write a book, spend more time with my piano...or just lie in the sun a bit more... I usually just keep plugging along doing what I have been doing... Soon to be 71 years old, I find the motivation to change my habits declining. And, I am gratified by the occasional "thank you for the blog" email that I get.
